[A Case of Solitary Liver Metastasis of Low-Grade Endometrial Stromal Sarcoma 31 Years after Resection of Primary Lesion].

A 73-year-old woman was referred to our hospital after a liver tumor was discovered during an abdominal ultrasonography. Thirty-one years ago, she underwent a total hysterectomy for uterine myoma and was diagnosed with a leiomyoma. Twenty years ago, she underwent a bilateral oophorectomy for an ovarian tumor and was diagnosed with a luteinized theca cell tumor accompanied by sclerosing peritonitis. A CT scan and MRI revealed a 65-mm tumor in the S6-7 of the liver. There was no sign of any lesions other than in the liver, and TACE was performed for suspected hepatocellular carcinoma. However, a favorable treatment outcome was unable to be obtained and a posthepatic segmental resection was performed. Histopathological morphology suggested a similarity to endometrial stromal cells and, considering the history of myoma of the uterus and ovarian tumor, immunohistological staining was carried out. The myoma of the uterus and the ovarian and liver tumors were all CD10(+), α⊖SMA(-), MIB-1 index 3%. The uterine myoma, which was initially operated on, was rediagnosed as a low-grade endometrial stromal sarcoma. After 11 years, ovarian metastasis was observed, and after 31 years liver metastasis occurred. Examples of resection of liver metastasis of endometrial stromal sarcoma are extremely rare and, we will include a review of the literature in this report.

Prediction of Postoperative Cerebral Infarction after Cardiovascular Surgery Using Quantitative Measurement of Cerebral Blood Flow with Brain Single-Photon Emission Computed Tomography.

Prediction of postoperative cerebral infarction after cardiovascular surgery is difficult. The present study investigated whether quantitative evaluation of preoperative cerebral blood flow used in the Japanese EC-IC Bypass Trial (JET) study is useful for the prediction of postoperative cerebral infarction after cardiovascular surgery. First, patients were divided into two groups based on preoperative cerebral blood flow. In an evaluation using preoperative imaging, patients with good or mildly decreased preoperative cerebral blood flow, divided into clinical stage I or II by quantitative evaluation showed no postoperative cerebral infarction. However, 24% of patients with poor cerebral blood flow who were categorized as clinical stage II, experienced postoperative cerebral infarction. The incidence rate was not statistically significantly different when the groups were compared. Second, patients were divided into two groups based on the anatomical area of the brain affected corresponding to clinical stage II. Patients with a 10% and greater brain involvement had a significantly higher incidence of postoperative cerebral infarction (38%) compared to others (0%, p<0.01). This method may be useful for the prediction of postoperative cerebral infarction after cardiovascular surgery, but a further prospective study is needed.

Early-phase wound healing and long-term outcomes of a selective endovascular-first approach for treating Rutherford 5 critical limb ischemia with infrainguinal lesions.

PURPOSE: To evaluate the validity of a selective endovascular-first approach for Rutherford 5 critical limb ischemia (CLI). METHODS: We analyzed, retrospectively, 51 limbs in 46 patients treated for Rutherford 5 CLI with infrainguinal lesions between 2010 and 2012. Endovascular therapy (EVT) and open surgical revascularization (OSR) were performed initially in 28 and 23 limbs, respectively. The interventions were assigned according to the systemic condition and femoropopiliteal TransAtlantic Inter-Society Consensus (TASC) II classification. We investigated early wound healing rates (defined as healing within 90 days) and amputation-free survival (AFS) rates in the EVT and OSR groups. RESULTS: The OSR group had more TASC D lesions (P < 0.0001). The early wound healing rate was significantly higher in the OSR group (OSR 46.1 % vs. EVT 14.3, P = 0.0205); however, the AFS rates did not differ significantly between the groups (P = 0.4031). Preoperative walking ability significantly influenced AFS (P < 0.0001). CONCLUSIONS: Our selective endovascular-first approach did not worsen AFS; however, OSR yielded better early wound healing rates. Preoperative walking ability strongly influenced AFS; hence, patients with good walking ability were good candidates for primary OSR. The indications for EVT for earlier wound healing still require better clarification.

Is Endovascular Aneurysm Repair a Relative Contraindication for Patients with Preoperative Renal Dysfunction?

UNLABELLED: Whether endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) is a relative contraindication in patients with preoperative renal dysfunction (Pre-RD), remains controversial because the contrast medium may induce nephrotoxicity. In this study 1658 patients were treated at ten Japanese medical centers between January 2005 and March 2011 (Open surgery (OS) vs. EVAR: n = 1270 vs. n = 388). They were retrospectively analyzed. Multiple logistic regression analysis (MLRA) with pre- and intra-operative variables was applied to all patients. The endpoints induced onset of new dialysis and postoperative renal dysfunction (Post-RD), were defined as a 50% decrease or more from the preoperative estimated glomerular filtration rate (eGFR) level. RESULTS: Early mortality, Post-RD, incidence of new dialysis in all patients were 1.6% (OS: EVAR = 1.9%:0.8%), 6% (OS: EVAR = 8%:2.3%) and 1.4% (OS: EVAR = 1.5%:1.0%) respectively. MLRA identified operation time, clamp of renal artery as risk factors for Post-RD, and operation time and Pre-eGFR level as risk factors for new dialysis. CONCLUSION: Although Post-RD was more frequently observed in the OS group, MLRA showed that the choice of OS or EVAR was not a risk factor for Post-RD and new dialysis. It was strongly suggested that using contrast medium during EVAR is not a contraindication to AAA repair in patients with Pre-RD.

Early outcomes of open abdominal repair versus endovascular repair for abdominal aortic aneurysm: report from national hospital organization network study in Japan.

OBJECTIVE: Early outcomes of open abdominal repair (OS) versus endovascular repair (EVAR) for abdominal aortic aneurysm were retrospectively analyzed, after commercialized devices for EVAR had become available in Japan. PATIENTS AND METHODS: A total of 781 consecutive patients (OS, n = 522; EVAR, n = 259) were treated at ten medical centers between January 2008 and September 2010. The OS group comprised patients with preoperative shock (SOS, n = 34) and without shock (NOS, n = 488). RESULTS: Patients in the EVAR group were 3 years older than those in the NOS group. There was greater prevalence of hostile abdomen, on dialysis, chronic obstructive pulmonary disease on inhaled drug, and cerebrovascular disease in the EVAR group than in the NOS group. Surgical mortality was 16 cases (2.0% in all patients, EVAR: 0.8%, NOS: 1.4%, SOS: 21%). Hospital stay >30 days was documented in 52 (11%) with NOS, 11 (33%) with SOS, and 8 (3%) with EVAR. Thirty late deaths included 6 aneurysm related death and 14 cardiovascular causes at a mean follow up of 1.0 year. The survival rates freedom from all cause death at one year, were 95 ± 1% in NOS and 94 ± 2% in EVAR respectively. CONCLUSION: Though significant differences in patient characteristics among three groups were noted, early results were satisfactory.

Thoracic endovascular aortic repair with homemade stent grafts: early and mid-term outcomes.

PURPOSE: We reviewed our experience with homemade stent grafts in the repair of a variety of thoracic aortic lesions. The objective of this study was to assess the early and mid-term outcomes of this therapy. METHODS: From 1999 to 2007, homemade stent grafts were inserted in 88 patients with an atherosclerotic aneurysm, dissection, pseudoaneurysm, trauma, or rupture in the thoracic aorta. The endoprostheses were stainless steel Z-stents covered by a polyester graft, and were custom-designed for each patient. RESULTS: Placement of stent grafts was technically successful in 81 of the 88 patients (92%). Within 30 days after treatment, 3 patients died, 3 had a cerebral infarction, and 3 had onset of paraplegia or paraparesis. Primary endoleaks were observed in 8 patients (9%). During the mean follow-up period of 32 ± 26 months, 7 patients had persistent endoleaks and 7 had stent-graft migration. The aneurysm-related mortality rate was 7%. The rate of freedom from open-surgery conversion at 32 months was 89.0%. CONCLUSIONS: Our early experience with elective and emergency thoracic endovascular aortic repair using homemade stent grafts provided therapeutic benefits to high-risk patients. Endoleaks and stent-graft migrations were the factors most commonly responsible for secondary intervention in the mid-term period. Careful follow-up of patients treated with this approach is needed to avoid major complications in the long term.

Clinical outcome of perioperative nonpermanent vena cava filter placement in patients with deep venous thrombosis or blood stasis of the vein.

PURPOSE: To evaluate the recent clinical experience with nonpermanent inferior vena cava (IVC) filter placement preoperatively, especially with regard to patients who had deep venous thrombosis (DVT) due to compression by a tumor or an aneurysm. METHODS: Preoperative prophylactic IVC filter placement was performed between October 2002 and March 2008 in 48 of 83 patients who underwent IVC filter placement. IVC filter placement was performed preoperatively in 35 of the 48 patients due to DVT located distally in an iliac vein or due to IVC compression by a tumor or aneurysm. This study examined the early and mid-term outcomes resulting from nonpermanent IVC filter placement. RESULTS: The mean implantation period was 11.1 +/- 9.3 days (range, 3-56 days). Three patients (8.6%) experienced minor complications during the IVC filter placement. A thrombus was captured in the filter in 4 patients (8.8%). One patient in whom the filter was left as a permanent filter died during the follow-up period. No patient experienced any pulmonary embolus during the follow-up period. CONCLUSION: Nonpermanent IVC filter insertion is perioperatively useful in surgical procedures that eliminate the compression of the vein by an excision of either the tumor or aneurysm compressing the vein.
